This utility allows to build Shake build systems using Cabal sandboxes. It automatically installs and updates a build system's dependencies, either from Hackage or from a local source directory. See the homepage for more information.

shake-cabal-build

Build systems written in Shake normally need to be compiled, see the Shake manual for more information. shake is a simple Haskell script that takes care of all the details. Using the Cabal infrastructure, build scripts are compiled on the fly for execution and also be reused as library components.

Installation and usage

Copy or link the script to your source folder. You can also install shake-cabal-build from Hackage with cabal install. The executable is called shake-cabal-build in order to avoid a clash with a different executable installed by Shake, you can create an alias with a different name if you want.

Write a file shakefile.hs containing Shake rule definitions and create a file shakefile.cabal with the following contents:

If you're using shake-language-c, add it to the dependencies as well. Refer to the Cabal manual for more information about configuration file features. cabal init is another way of creating the Cabal file. It can automatically pick up the dependencies referenced from package imports in your shakefile.hs (if it exists already).

./shake .init initialises the sandbox and configures your package. This might be necessary sometimes but usually you don't need that command.

Running ./shake with any argument not starting with a . runs your build script with the arguments passed on the command line, usually Shake options and targets to build.

Cabal file extensions

The shake script supports the custom Cabal configuration setting x-shake-package-dirs. It allows to specify Cabal source packages that should be added to the sandbox with cabal add-source, for example:
